河套灌区秋浇定额合理优选的试验研究

Experimental Research on the Rational Selection of Autumn Irrigation Norm in Hetao Irrigation District

秋季储水灌溉是内蒙古河套灌区一种特殊的灌水制度,它牵涉到在黄河水紧缺的条件下,如何节约水量,进行合理灌溉的问题。通过土壤含水率、土壤盐分、地下水位的变化与秋浇定额关系的试验研究,确定出切实可行的秋浇定额,实施科学、合理的秋浇制度。

Autumn water-storing irrigation is a particular irrigation regime in the Hetao Irrigation District of Inner-Mongolia. However, it involves problems of how to save water and how to allocate irrigation water rationally under conditions of water shortage of Yellow River. Through experimental researches on the relations between changes of soil moisture, soil salinity, groundwater table and autumn irrigation norm, practical and feasible autumn irrigation norm is determined to realize scientific and rational autumn irrigation.
